IMPROVED UAB-GOUPLING.

TO ALL Wl-IOM IT MAY CONCERN:

Be it known that I, JOHN I). SPANGLE, Of Hopewell Centre, in the county of Ontario, and State ot' New York, have made new and useful improvements in Oar-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, which are made part ot' this specification, and in whichi Figure 1 is a front view.

Figure 2 is a plan or top view,

Figure 3 is a view of the under side, a portion being in section.

Figure 4 is an end view showing the catch.

Figure 5 is a vertical section on the line a' ef, tig. 3, to show the India-rubber pad which retains the link in its proper presentation to the approaching draw-head.

The design of4 my invention is to provide a self-coupling arrangement for railroad cnrs, and the improvements consist, first, in the jointed coupling-pin lever, which admits of' the horizontal motion of the pin as tho draw-head strikes; second, the arrangement ot' the lower lever connected to the pivoted hook and draw-head at its respective ends, and operating automatically by the inipingement of either the draw-head or the link.

In the drawings A. is the frame of the cnr; B the draw-head; C D a jointed lever pivoted to the standard L, which is attached to the body of the cnr; E is the coupling-pin, pivoted to and suspended from the end of the jointed lever above spoken of; F is a hook, pivoted at I to the side of the cnr so as to engage with the projecting handle of the lever C D when thc said handle is depressed and the coupling-pin elevated ready for the coupling oi' thc cars; G is a lever pivotcd to the under side of the car :1t O, the lower portion of the hook F entering a slot in its outer end', while the inner end enters into engagement with the draw-head D, which latter is continually pressed outward by the spring M contained therein; K is the coupling-link, and I the inside ot' the draw-head; II is the spring, which elevntes the handle of the lever C D when detached from the hook, and throwing down the pin E.

The operation is as follows 'The coupling arrangement being in the position shown in lig. l, the pin is raised ready for the approaching car which 'carries the link, as seen in the View, iig. 3, which represents the under side. By the contact of the link with the end of the recess I in the draw-head the latter is pushed back, collapsing the spring M, and by the vibration of the lever ti detaching the hook Il from the handle of the lever C D, which falls, the pin E coupling with the link K. It will be observed that the pin E maintains its position at the end ot` the lever C D, and is never entirely withdrawn from its opening in the draw-head, and as the latter moves longitudinally of the car when vstruck by the link or draw-head ot' the approaching car, the pin moves therewith by the permission ot' the `joint, which attaches the portion D to the portion C. The link K, as willbesecn by reference to/lig. 3, is maintained in a horizontal position, so as t-o enter the open mouth of the approaching draw-head by means of the elastic pad W, of India rubber or analogous material.

Having described my invention, what I claim therein as new, and desire to secure by Letters Patent, is 1. The `jointed upper lever C D, in combination with the coupling-pin and the receding draw-head, operat` ing substantially :is described,

' 2. The lower lever G, in combination with the hook F, the spring M, und draw-head I, operating substantially as described.

The above specilication of my improvement in car-couplingsl signed by me this 5d day of March, 1866.
